Comparison of gene expression profiles from Nothobranchius furzeri (strain: MZM-04/10p) brain for 2 age groups after physical exercise (swim-tunnel). For physical exercise, fish were placed in swim-tunnel for 4 weeks and were swimming 6 times per day for 5 min duration (water velocity 14 cm/s). The RNA-seq data comprise 3 groups. Jena Centre for Systems Biology of Ageing - JenAge (www.jenage.de) Overall design: 20 samples in 3 groups: 9 weeks w/o physical exercise (5 Samples), 9 weeks w/ physical exercise (5 Samples), 27 weeks w/ physical exercise (10 Samples)
